On page 84, on the derivation of the Leith/Lax-Wendroff method by the MMOC (Modified Method of Characteristics), it is stated (after Eqn. 3-223) that linear
interpolation over (i+1) and (i-1) produces the FTCS method. This is incorrect, as pointed out by Prof. B. P. Leonard. In order to derive FTCS by MMOC, one would need to use an unnatural "interpolation" that
does not reproduce the node-point values at (i+1) and (i-1). In fact, linear interpolation over (i+1) and (i-1) produces the Lax method (page 263, Eqn. 5-32).

The running head at the top of the verso (left) pages of Chapter 5 is incorrect. Rather than "Incompressible Flow Equations" it should be "Basic
Computational Methods for Compressible Flow."

A recent reference for vorticity wall boundary conditions is the following.
